As already suggested, use XDC command againist to the job name in SPOOL then press enter, there you can see pop up screen to provide data set which is already cataloged, specify the data set name, then press ENTER

press f4,
issue pre,shift+tabkey,
control move to last user(i.e recent user) ,
there alyways we r give' ?',
insted of that ?-mark we can type 'XDC'.
at that time ,it will ask one pds name.
there we can give that pds name with disp status.
then the data in spool will move to pds member.

If you needed to add DCB info to the DDname to make it work it means the program is NOT providing it. SOmetimes the LRECL, RECFM and even BLKSIZE maybe coded right in the program so the parameters may be omitted from JCL.
